The present invention relates to improvcments in cane harvesters, and has for an object to provide an automatic machine for cutting the cane stalks and subsequently 5 topping the saine.

Another object of the invention is to provide a simply constructed7 compact auto matic machine for stripping the leaves from kthe stalks, severing the stalks and topping the same.

A further object of the invention resides' in providing an improved cane harvester constructed and arranged to cut the stalks at a low point to avoid a wasteful high stubble and to remove the tops uniformly a predetermined distance from the bud irrespective of the length' of the stalks thus placing the cane immediately without subsequent operations in shape for the mill.

'Vi/'ith the foregoing and other objects in view, which will become immediatelyv apparent to those skilled in this art, the invention will be described more particularly hereinafter and more fully ypointed out in the lappended claims.

Referringmore particularly to 'the drawings, ladesignates the longitudinal beams, of which there are two or more, of the main framework, and 16 represents the cross beams which are welded or otherwiseattached to the longitudinal beams l5.

The main frame is arranged to be supy ported for movement upon tractors, for instance the endless tractor belts l? which are engaged about the rear drive druiLs 1S and the forward idler drums 19. fis shownr in T1" i i v 1 i iguie 3, pieferably two such endless tractors are employed, the shafts 20 and 2l of which may be mounted in appropriate bearings in the longitudinal beams l5 and any other longitudinal beams 30 mounted upon the cross beam 16 ljust in e of the ezuiless tractors. lt vviil be unoei i' that the shafts 9,0 and 2l of the tracA 'f arcstub shafts which do not extend ely across thc framework, the cen' is occupied by a secondary or supililementalframe capable of a rocking movement which would otherwise be impeded were the shaftsA to entend the entire transverse width of the machine. Y y

The supplemental frame consists in the, embodiment shown in the drawings of a number of longitudinal beams 23 connected by cross beams 2li.

As shown inA Figure 2,the supplemental frame is provided with'hangers or bearings 25 upon which it is hung' for rocking movement upon the inner p ions of the rear stub shafts 2O ofthe tractors, thus enabling the supplemental frame to rock in a vertical direction upon the main frame, ther fulcrum il portion of which Y hinge plates or links B-l. i

of movement as required in the accommodating ol' the machine to the irregular contour ot the ground over which moves.

The rotary saws 26 and 27 are preferably in the .form of discs being disposed in a generally horizontal plane at the forward central portion of the frames and being overlappedpto insure the cutting through ot the cane stalk. lt is preferred that the cutting discs or saws 26 and 27 be given a slight cant or inclination with their loi 'ard edges disposed at a lower level than the rear edges.

l am thus enabled to get a very desirable lea d which will 4acilitate Ithe severing stalks and will also dispose the leading c olthe saws at a very low point `in the grou l it being my desire to remove :is much o lower surfaces of. the saws from contact friction with the ground over which the. nia- ;-liine is passino:

The saws are held at proper horizontal position by means of runners or shoes 2S having upturned front and rear ends te la Qlitate movement along the f 'onnd in either 'forward or yreverse direi, ions. These runners are carried'upon posts@ whiclrextend th spaced pins 30 andk up and are provided wi 3 l for engaging respeotr v above and below the onter'reduced ends o2 ot the outermost l'mgitudinal beams 23 oi the auxiliaifv trame. The pinsrequire the lor-ward end ot the auxiliary frame to ride up and` down with are additionally` pivoted as indicated the runners 28. The posts Q9 :i

or links Bel are in turn pivoted indicated at to the main frame.

hinge plates 37 arepivotally coupled to the iain frame at 3S and to the posts at 39.

The pivot pins also serve to si'ipporii the posts si() through which the shells Ll-l o l" the rotary saws 2G and 2T ex Y id. The ruiniers QS are carried on shanks l2 tilting up through the posts Q9 and having set screws `rlo to hold the shanks ad'iustably 'in position. ln this way the height oli the shoes or runners be adjusted and the degree olr o'li'the saws accordingly re i blocks ell are shown as carried by portion ol 'the suppl-einentary i the saws. These lmnfing blocks incline downwardly and 'forward Each bearing block carries two shall a forward shalt y pensi ifa-.ti ou Llo and a rear shaft 4;". Front and rear brushes /li' and 48 are mouiited upon the lower portions oi these shafts, so that the planes ol" the brushes are diagonal to the plane ol the saws. 'llhe four brushesare shown in Figure 3.

The jfront and rear brush oli each pa r overlap and the front brushes or opposi pairs overlap. These brushes are driven in the same direction the saws with the near edges moving together reerwzfrzilly, whereby to push the cane on to the conveyii'ig apparaese hinge pl ates.

Lower links ortus. The diagonal arrangement of the brushes will also serve to leave the butt portions ot the recently severed cane in position to be grasped between the two adjacent rearwardly moving runs 9 and 50 olf the lower conveyor belts which are mounted upon the supplementary 'frame 'lor travel in a genen ally horizontal direction. lhese adjacent runs 49 and 50 oli the belts are subjected to strong pressure 1from rolls 51 under the urge of coil springs 52 or other appropriate means.

The forward bights ol'Y the conveyor belts are trained about the spi-ing-pressed idlers 53 and 5l. The 'foremost pair of pressure rolls 5l, as shown in l `igure 2l are ol'i'sct backwardly ironi the tranrsverse line connecting the rollers 53 and lo causo portions of the belts toiconvorge rearwardly and to provide a tapering mouth which will guide the butt ends o'l the stalks between the inner runs 0l the belts by which they are vfirmly graspedand moved rearwamlly. The

rolls 5l may yield locally and individually lo accommodate butts ot varying diameter and to compensate in general for dillferenccs in shape.

oli the frontends ot the lower belts i9 andi 50, the arrangement beingsuch thatthe top portion of the stalks shall-have become engaged and properly positioned by the brush mechanism to be hereinafte described before the upper conveyor belts take hold. The upper conveyor belts cooperate wi n thelower conveyor belts in holding the lower portions of the stalks at separated points to prevent the stalks 'from slii'liiingout ol' the. positii'm alter having been released by the topping mechanism.

Thetopping mechanism is also carried by the supplemental trame andis disposed above the conveyors. i". Y iper-strinature or topping' frame is mounted upon the frame to support the topping mechanism. This frame consists in general oli' longituifliinal beams 57 suitahbY suoiorted u )on the supplementary frame; and rear standards 58. rflic rotary` toppingrsaws are indicated the forward lower conveyor bel-ts a second,

supplemento l Z One nut is disposed aboveL liifi yThe super-structure also supports a rotary brush 67 of large diameter and a second rotary brushv 68, preferably longer than the first mentioned brush but of considerably smaller diameter.y A' thin bar 69 isv disposed between the brushes. The upper portions of the cane stalks are fed between the large brush 67 and the bar 69. It will be noted that the axes of the two brushes are disposed upon substantially the same angle' as the bank of topping saws.

Both brushes are rotated in the `same dir Vction. As looked at from the top portion in Figure l the direction of rotation is clockwise, so that the lower yportions of the brushes move toward the topping knives. The topping` knives are disposed below the lower edge of the bar 6 9 and below the smaller brush 68. The brush 68 is disposed adjacent the bar 69 and receives the tops of the cane stalks as they are freed from between the brush 67 and bar 69. The large brush 67 will throw the tops overA toward the narrower brush 68 and this latter brush which is rotated at very high speed further throws lthe tops with Great force in `Contact with the rotary topping `knives 59 by which the tops are severed at the requisite distance from the bud. The stalks of smallest height will be liberated first at the-forward lower portion of the brushes 67 and 68 due to the inclined positioning ofthe same; while the tallest stalks will be liberated last-or only at the higher rear portions of the a brushes. The knives in like manner progress upwardly at a constant spacing rfrom the brush 68, sothat the topping is carried out uniformly, that is at the same distance from the bud irrespective of the length of stalk. In this connection advantageis taken of the tendency of the stalksfcaught between the brush 67 and bar V69 to seek a position with the length of the stalk disposed at right angles to the axisof the br'ush67.

The brush 67 willcause the stalks to take This vis accomplished whiley the butt yis in the lower conveyor only and before it arrives and is doubly grasped by the upper conveyor which would then render it difficult for the stalk to take up any newpcsition of inclination '1ttempted to be imposed upon it by the action of the brush 67.'V y

As soon as this right angle or angular position is taken up by the stalk with reference to the brush 67, the stalk moves into engagement with the second conveyor, which aids to more rigidly support it and carry it back to the rear of the machine. In this Vwaythe tops are all' uniformly treatedby the vbrush 67 and its bar 69. The topping is consequently uniformand standard.- The brush 67 also has a separating and winnowing action on the ystalks which are often received in clusters..

rlhe stalks are separated and shifted along separately by the brush 67 thus enabling each stalk to receive individual treatment as to topping.

The cutting apparatus 1s preferably precededby a stripping' and stalk supporting device composed of a frame 70 of anyfappropr-rate construction having mounted thereiunumbers of pairs of brushes7l and 72.k

In the instance shown there are three such pairs of brushes, one pair being super-imposed above the other.k The brushes are mounted on shafts 7 3 and 7 et that are mounted substantially horizontally and have theiry axes extending substantially forwards and n ceive the stalks. The rear open side of they frame is disposed adjacent the receivingend of the brush 67 and its bar 69. y c

Pairs of small flat brushes 76 and 77 with their axes substantially vertical are mounted in connection with the brushes 7l and 72 and their function is to engage the cane stalks when in the rear portions of the brushes 7l and 72 and hastenthe disengagement of the stalks from said brushes 7l and 72. T ie front frame 70 is pivotally carried by the axles Q1, so that it may move up and down. rlhe front vportion of this frame 70 is mounted uponthe casters 78Vwhich are swivelly ca riedcby the frame and move along ldirectly in contact with the groundV yielding up and,v

down inl accordance with inequalities in the surface level. The side beams l5 of the main frame are continued outwardly as at 79 to embrace the lower beams 80 of thev front frame 70. The extended ends 79 act to reinforce and support the sides of the front frame 70, ,which has a tendency to bulge out under the action of the cane stalks entering between the pairs of brushes '7 l yand 72. Lugs 8l are carried by the front frame in position toengage and rest upon the cvtension beams 7S), whereby to preventr the forward portion of the' front frame from descending to a too low level and to prevent the castors 7 8 getting in ditchesand holes and quarter-drains from which they would not emerge without mounted, as illustrated in Figure 8, at oney side of the rear portion of the auxiliary frame and having the crank shaft 83 journaled in lllf) driving drums 18 ot the endless appropriate bearings. A sprocket 84 on the crank shaft is arranged to receive a chain 85 which extends do.vn\vardly and is trained about a second sprocket 86 'for driving the mechanism ot the change-speed device 87. rl"hi's device may be a usual Ytorni et transmission employed upon motor vehicles for driving the propeller shaft indicated at 88. In the propeller shaft are preferably ineluded the universal joints 89 and 90 and a slip joint 91 for compensating for the relative vertical movement of the suppien'xental l'raine on whichV the power unit is mounted. rlhe propeller shaft 88 is arranged to drive a ditl'ercntial 92 mounted upon the main iframe.

The driven transverse shafts from the diilerent-iai are indicated at lll-3 and carry sprockets 94 coupled by the chainsI 9o to the larger sprockets 96, which are mounted upon the trattors` The crank shaft 88 ol the engine is pro` vided with a .lined pulley wheel 97 engaged by the twist-ed ielt 98 by which power from the engine is transmitted to the small pulley 100 and the larger pulley 101, mounted on the shaft 107 journaled in the bracket 09. 'Ehe belt 98 is engaged about the wheel 100 ot smaller diameter, while the driven wheel 101 of larger diameter receives Vthe twisted belt 102. This latter belt engages and drives a pulley 108 on the shaft' ol the ltopping brush 67. The shafts of both brushes 67 and 68 are extended outwardly and provided with sprockets 104 and 105, the same being engaged by the chain 1067 whereby both brushes will be driven in the saine direction. The sprocket for the topping brush 67 will be larger than the sprocket tor the brush in order to drive the atteibrush at higher speed.A

As shown in Figure the shalt 188 is provided with a pulley 200 engaged by a twisted belt 201 which is also trained about a smaller pulley 202 on the sha'it 208 carried in a bracket 204. On the` shalt 203 is lined a bevel pinion 108 meshing with a companion bevel pinion 10) lined on the shaft 110. This shaft 110'is the rotary topping lkniilie drive shaft and includes universal joints 111 and 112 and a slip joint 118 as shown in Figure 1 to permit of the adjustment et the topping knife assel'nbly. rllhe drive shaft 110 is coupled to a d rive pulley 114, as shown in Figure 8. This drive pulley 114 is engaged by the belt 115 which tiainedabout the pulleys 116 upon the saw shafts '117 and the idler pulleys 118.

The crank shaft 83 ot the internal combustion motor at its rear end is provided with a bevel pinion 119 disposed in mesh with a bevel pinion 120 on a vertical shaft 121. As shown in Figure 5. the lower end of the shaft 121 carries a iined'bevel pinion 122 meshing with a similar pinion 128` on the'trzuisverse shaft 124, which carries the pinions 125 and 126 for engaging with companion bevel pinions 127 and 128 upon the belt drive shafts 129v and 180.1 These belt drive .shafts are pro vided with the driving drums 131 and 132 by which both lower and upper conveyor belts are driven, The transverse shaft 124, as shown in Figure 5, is provided also with a bevel pinion 138 engaging a bevel pinion 134 upon a vertical shaft 185 having a second bevel pinion 18 which meshes with the bevel. pinion 137 on the shaft 138. This shaft 188 is mounted in appropriate bearings in the supplemental 'frame and extends forwardly for the purpose ot' transmitting motion to the rotary saws, rotary brushes and the stripping and stalk holding device. At the opposite side ot the supjiilemental frame, namely at the ending side7 is a similar line sha it 80 being an extension of the crank shatt of the engine 82. These shafts 138 and 189 are provided with pulleys 140 and 141 'tor connection to the twisted belts 142 and 148 which in turn engage the pulleys 144 and upon the shafts 45 o1' the lowermost brushes 47.

is shown in Figure 2, the belt and pulley connection 146 is mountedbetween the shafts and 46er1 each pair ot brushes 47 and 48.,A

so to drive the brush 48 from the shaftv ot the brush 47.

The line sha'its 138 and 139 are also provided with the pulleys 147 and 148 for oonnection to the twisted belts 149 and 150. These belts engage the pulleys 151 and 152 on the shafts 41 of the rotary saws. The saws' the lower portions ot the severed stalks inl toward the brushes 47.

Theline shafts 188 and 189 are ar 1anged to drive through the chain and sprocketmechanism 15 and 156 the Counter shafts 157 and 158 journaled in appropriate bearin gs in the supplemental frame. These counter shatts extend'torwardly and include universal joints 159 and 160 and the slip joints 161. shafts carry the fixed bevel pinions 162 arranged to mesh with and drive the bevel pinions 168` on the cross shafts 164. These latter shafts are provided with the bevel pinions 165 meshing7 as shown in Figure 4, with the bevel pinions1166 at the lower endso'l the vertical drive shafts 167 a-nd`168. Bevel pinions 1,69 fixed on the shafts 167 and168'V are disposed in mesh with similar companion bevel pinions 170 on the shafts of the rotary brushes 71 and 72. Pulleys 171 on the shafts 167 and 168 are engaged by crossed belts 172 At their forward ends the counterl lili) A for driving the pulleys l 7 3 on the shafts of the brushes 76 and 7 7 Inl operation, the machine progresses through the cane lield at the selected speed,Y Abeing driven by the internal combustion or other motor 82 through the selective transmission 87, which will be under the control of the operator of tne chine in accordance with standard automobile practice. The endless tractors upon which the machine moves will enable the device to proceed over ground of rough or soft character, such as is usually encountered in cane growing countries. The advancing machine initially receives the stalks between the pairs of brushes 7l andv 7 2 and should any of the stalks be beaten down or lying low, the same can be raised by the pilot shoes 174, which will lift and guide the 'fallen or bent stalks up into an erect'position or into a position parallel with the line of travel of the machine whereupon, on'advance ot the machine all of the stalks y will come under the influence of the brushes 7l andv 72. By virtue ot the direction of their rotation, these brushes 7l and 72 will have a tendency to raise the 'fallen stalks and to hold the standing stalks in an upright position best suited to severing the sameby the rotary-knives 2G and 27. The brushes 7l and 72 also have the etlect to strip the leaves from the stalks and to present the bare stalks to rthe cutting and topping mechanism. The

'stock of the brushes will preferably be of steel rwire to sustain the great strains put uponA same. rlhe machine by its movement will bring the saws 26 and 27 which are rotating at a relatively fast speed intocontact vith the stalk-s." These stalks will be held in position by the brushes 76 and 7 7 against any tendency to back away from the knives y during the severing operation. As this severed operation proceeds the severed butt ends of the stalks will come under the influence of the rotary pusher arm's 153 by which they vill loe forced backwardly' into engagement with 4the rot-ary brushes 4:7. rlhese brushes due to their inclination will exert a lifting effect on the stalks. The stalks are passed along to the upper brushes 48 and into the receiving endoit the lower conveyors 49, 50. At

the same time the upper portions of the stalks are guided between the brush 67 and The stalk will then be made to asitsbar 69.

right angular position above resume the ferred to. 55, 56 will engage/,the stalk Just above the butt, and 'due to the action or the two con veyors and the rotary action of the brush 67 the stalk 'is carried rearwardly. The top portion of the stalk will be released from the brush 67 and bar 69 at a pointy governed by the height of the stalk, and promptly on its release the top will be pushedV by the Yrotating brush 68 against the topping knives andthetopping willtake place in all cases Subsequently, the upper conveyors Y at a predetermined distance from the bud which will. be the same distance for all stalks irrespective of length.

The tops may be simply thrown over the side of the machine or collected in a receptav cle supplied for the purpose. The stalks may be vcarried to the rear of the machine and dumped upon the lield by the conveyors, or they may be collected'in trailer provided for this purpose.

lt is obvious that va lious changes and modifications rmay be made in the details ot construction and design of the above specifi-` means for receivinp` lthe top portions of ther 'stalks and moving same along with the conveying means whereby due to the inclination the tops ot stalks of varying length-s will be releasedto the topping means at ay variety of points to secure uniform topping.
